Information needed about a dealer and new car purchase

I ordered my Avalanche on January 9th and I called the dealership the other day to ask them to E-mail me a copy of the options that I ordered. Before I could get a word out the salesman started explaining to me that because I ordered so late that theres some kind of delay and that he was do everything he could get to the bottom of this problem. I did alittle research myself and found out the dealership hasn,t summitted a request for the build yet. I also found out someone put in their order on jan. 19 and received their Avalache on 2/28/2013. Whats going on? Why am i being given the runaround ?
